FBI releases Clinton email investigation files

Washington: Hillary Clinton told FBI investigators during an interview in July that she had used a personal email server as secretary of state "out of convenience" and did not remember anyone raising legal concerns about the practice, according to documents released on Friday.

Clinton also said that she "did not recall receiving any emails she thought should not be on an unclassified system," the FBI documents say, The New York Times reported.

"She relied on State officials to use their judgment when emailing her and could not recall anyone raising concerns with her regarding the sensitivity of the information she received at her email address," according to the documents.

Her comments were largely consistent with what she has said publicly about the email controversy in recent weeks - although Republicans maintain that she has contradicted her earlier testimony to Congress on a number of key points.

On Friday, the FBI released its interview with Clinton, along with a memorandum summarising the investigation into her use of a private email server that contained classified information. 

The document summarizing the Democratic presidential candidate's interview, known in the FBI as a 302 report, runs only a dozen pages. 

The memorandum is lengthier, and goes into greater detail about aspects of the case. The materials were presumably provided to James B. Comey, the FBI director, who later decided to not recommend charges in the case.

A senior law enforcement official said the interview at FBI headquarters had been intended "to fill the gaps" of what the FBI did not know about why Clinton decided to use a private email server.

Both documents were partially redacted, which slowed their release as the bureau sought to protect sensitive information while satisfying the public's right to know.
